Henoch-Schönlein purpura and systemic disease in children: retrospective study of clinical findings, histopathology and direct immunofluorescence in 34 paediatric patients

Abstract

This study suggests that in children with HSP, microscopic dermal oedema and C3 on DIF may be predictive of renal involvement. Patients with clinically apparent oedema and lesions above the waist are more likely to have gastrointestinal involvement.
